Ryan O’Neal is prepared to fight to clear his name over the mystery surrounding a $30 million Andy Warhol painting of his former lover Farrah Fawcett, RadarOnline.com has exclusively learned.

The painting was a part of an art collection bequeathed to the University of Texas by Fawcett in her will. (Fawcett had studied art there).

Fawcett’s estate has yet to be settled, but in the meantime, University of Texas officials are looking for some of the artwork -- in particular a 1980 Warhol portrait of the former Charlie Angel’s star.

Alana Stewart has told RadarOnline.com that there is NO controversy surrounding Ryan O’Neal’s donation of Farrah Fawcett’s famous red swimsuit to the Smithsonian Museum.

Several observers were surprised that the late star’s former life partner handed the bathing costume over to the illustrious historical exhibition because it had not actually been left to him in her official will.
